Patented Nov. 26, 1940 UNITED STATES PATENT oEElcE 2,223,229 y TOILET SEAT., Alexander Schwartz, New Yorkf. Y. Application January s, 1940, serial No. 312,901 4 claims. (el. 4-237) My invention relates to toilet seats and has particular reference to toilet seats and covers made of corrugated paper. 5 My invention has for its object to provide a light and inexpensive seat made of an ordinary corrugated board by winding a strip of such board on a suitable form or mandrel, the width of the strip corresponding to the thickness of the board, so that the corrugations of the board extend transversely of the board. Due to such arrangement of the corrugations, the board, when nished, is very strong and resistant to bending and warping. Being soundproof, the seat or cover made by this method does not produce any objectionable noise when dropped on its place over a toilet bowl and cannot possibly damage the latter.

Another object of my invention is to provide means to close the spaces between the corrugations at the surface of the board in order to obtain a substantially smooth and continuous surface, suitable for enameling orv covering with a layer or llm made of a smooth waterproof material such as Celluloid, etc. I attain this object by employing corrugated board comprising a flat sheet of relatively stiff or hard paper to which a corrugated sheet is glued, the latter being made of relatively soft paper. The seat or cover, when fully wound, must be trimmed or milled so as to obtain the required shape with rounded edges. Instead of trimming the edges by ordinary methods such as are employed in woodworking industries, as by cutting with rotary knives, I employ grinding, filing or rasping tools for this purpose.

It should be noted that ordinary cutting or trimming operations remove uniformly both the at and corrugated paper, leaving holes between the corrugations which must be lled by a suit- 'able plastic or cementitious material in order to obtain a smooth surface.

I have found, however, that my grinding `or rasping tools, While smoothly removing the edges 45 of relatively stiif, flat paper, do not fully remove the exposed portions of the relatively soft corrugated paper, but largely mash and spread the edges until they completely fill the spaces between the corrugations at the surface of the 50 article. By continuing the rasping or grinding operation afterthe spaces between the corrugations are iilled, a substantially smooth and uninterrupted surface is obtained which can then be made waterproof by ordinary methods and final- Cil `55 v1y enameled .or covered with a *sheety of Celluloid or similar smooth and waterproof v material.

Another object of my invention is to provide means to wind the corrugated strip in such manner that the seat will have an oval shape inside while on `the outside its oneend will be substantially straight as requiredfor` attaching hinges. Ihave found that the most satisfactory method of obtainingsuch a result is by winding -separately the inner and outer portions of the seat or cover and `joining together the two portions. The outer portion is wound kon an oval mandrel or form of a required shape, having one end cut oil to make vit substantially straight, and the inner portion is wound on an oval mandrel or form so as to obtain an oval opening inthe center. The peripheral contour of the inner portion is madeto correspond to the inner contour of the outer portion except where the latter is straightened out atthe end. 'I'he inner portion 0 has one end partly cut off to make itfit the inner straight end of the outer portion. The inner portion is insertedvinto the outer portion and is cemented in its place.

My invention is more fully described in the 25 accompanying specification -and drawing, in

Fig. 8 is afdetail view of a hinge attachment. 45 My toilet seatconsists of two portions I and 2 as shown. in Figs. 1, 2 and 3. These portions are vmade of long strips of corrugated board wound on a suitable mandrel or form which is removed upon completion of the Winding. The corru- 5 0 gated board consists of a flat sheet 3 of a rela-l tively thin and stiff paper and a corrugated sheet 4 of a relatively soft and flexible paper which is glued to the surface ofthe flat sheet. The strips are so cut that "the corrugations extend transversely as shown in Fig. 5. The board made of such corrugated board is therefore highly resistant to compressive and bending stresses as well as warping, being at the same time very light. The successive turns of the strip are glued together' in the process of winding the seat vor p cover, the starting end 5 being trimmed or scariled to provide a smooth surface.

YThe mandrel for the outer portion I is flattened at one end as shown in Fig. 2, so that the outer portion I has lalso a flattened or straight end portion at 6 inside and at 'I outside, as is necessary for attaching hinges 8 (Fig. 5). drel is of an oval shape so that the inner portion has an oval opening in the central portion. The'shape of the mandrel is such that the outer contour of the portion 2 exactly corresponds to the inner contour of the outer portion IY with the exception of its flattened or straightened end.

In order to make the portion 2 t in the openf ing in the portion I, the end of the portion 2 is cut off at 8 as shown in dotted lines in.Fig. 3. The inner portion is then inserted into the outer portion and is cemented or glued in its place inside the outer portion. Both portions can be Wound in the same manner, with the corrugated paper to the inside as shown in Fig. 2. The eX- cess corrugated strip may be then removed from the inner side of the 'portion 2. It is also possible, of course, to wind the inner portion .with the ilat side of the corrugated board to the inside, gluing together the corrugated strips 6 at the place of joint of the two portions, or removing one of the strips 6 to `facilitate the gluing of the two portions. y

For attaching the hinges', inserts 9 aretted into the board. The latter is drilled for this purpose edgewise as shown in Fig. 5, or trans'- versely as shown in Fig. 8, the inserts being ce` mented or glued in the drilled holes.v The inserts may be made of a suitable machinable material. such as Wood or a plastic composition, and are drilled and tapped for screws I with which the hinges 8 are attached. v

The cover, Fig. 4, is made in a similar manner and consists of the portions Il and I2, wound separately and glued or cemented together as described. The only diilerence is that the inner portion I2 is wound on a relatively small mandrely I3 made of a machinable material, which is permanently cemented in its place so that the board has no centralopening. f

The seat, when completed, is trimmed on the outside in order to provide it with rounded edges. I have found that very satisfactory results'are `obtained by grinding or milling the edges of theY board and its surface with special rotary tools I4, Fig. '7. The tool is made in the formof a milling cutter of a required shape and is provided on its Surface with a plurality of small sharp projections I5 of the substantially same shape as are formed on ordinary rasps or coarse files. i

The sharp points of the projections I5 remove particles of material` fromv the surface' of the board, the particles being then immediately thrown out by centrifugal force, so that the tool remains clean and free from clogging by the removed particles. f

I have also found that this tool lcan 'be used to advantage for closing the spaces between the corrugations at the surface of the board. I use lfor this purpose the corrugated paper which has a vrelatively thin and stii flat paper 5 and relatively soft and thick corrugated strip 6. The

The maniiat paper 5 is ground clean and smooth by the tool, while the corrugated strip, being rather soft, becomes largely mashed and spread around, completely filling the spaces between the corrugations, as shown in Figs. 6 and'l. The flat side of the seat can be ground in a similar manner by using a fiat round rasp-like tool. The surface of the seat, When trimmed or ground by my tool, becomes smooth and continuous, without any holes which are closed by the expanded edges of the corrugated strip 5. `'Ihe surface can be then sprayed or otherwise covered with 'a suitable hardening substance such as glue or liquid glass.

'It may be finally polished when dry and covered with fa suitable enamel, or a separate envelope may be attached to the surface, molded of a suitv able plastic composition like Celluloidj fiber,

etc.

' seat, if desired. The 'cover can be made by molding from a'suitable sheet material, such as Celluloid, etc.

It is understood that my toilet seat may be modified without departing from' the spint of the invention, as set forth in the appended claims.
